UNIX file permissions are typically represented using a combination of characters: r (read), w (write), and x (execute). These permissions are set for three different categories: the file's owner (user), the file's group (group), and others (other). A typical permission set might look like rw-r--r--, where the owner has read and write permissions, while the group and others have only read permissions. This symbolic notation can also be represented numerically, with read as 4, write as 2, and execute as 1, making the previous example 644.
